QT4 How to blur QPixmap image?

I am looking for something like one of the following:

Blur(pixmap); 
painter.Blur(); 
painter.Blur(rect);

A Gaussian blur is a simple way to create a blurring effect.

Edit: And lo, I came across Qt's QGraphicsBlurEffect. Introduced in Qt 4.6, it seems to do exactly what you want.
